Revision 7 of this benchmark created on

Description

Just read about it today and here's a Test-case.

http://www.fairwaytech.com/2012/03/prefix-vs-postfix-increment-and-decrement-operators-in-c/

-- Added short versions of the for-loop

Setup

var tab = new Uint8Array(1000);

Test runner

Ready to run.
